APTT (Activated Partial Thromboplastin Time)

14 Azn

It is an indicator of the activity of the blood coagulation system, characterizing the formation of prothrombin and thrombin, and serves as a coagulation test. Activated partial thromboplastin time is widely used to monitor heparin therapy.

It is recommended to have the blood test in the morning, 8–14 hours after dinner, on an empty stomach (water is allowed), or 4 hours after a light meal in the afternoon.
Before the test, avoid increased psycho-emotional and physical stress (e.g., exercise) and alcohol consumption.
